Earlier this week, Google announced that it upgraded the satellite imagery on Google Maps and Google Earth with data collected from Landsat 8. With finer detail, more accurate colors, and a faster rate of capture, these new images from the US government make Google’s consumer-facing services better than ever.

Amazon is privately testing Wi-Fi technologies on licensed frequencies that belong to satellite service provider Globalstar. Called TLPS, it has the potential to become a uniform globally available terrestrial wireless network.

DARPA has begun development of a wireless communications link that is capable of 100 gigabits per second over a range of 200 kilometers (124mi). Officially dubbed “100 Gb/s RF Backbone” (or 100G for short), the program will provide the US military with networks that are around 50 times faster than its current wireless links.

Once something gets into the Earth’s orbit it tends to stay there, even after its useful life has ended. That has led to the collection of vast amounts of space junk surrounding our planet and more than a few headaches for anyone tasked with launching or maintaining a satellite.
